The Chebyshev(ODE, y(x)) command finds the solution of a Chebyshev equation, which is a linear homogeneous ordinary differential equation of the form:

Use the option output=steps to make this command return an annotated step-by-step solution.  Further control over the format and display of the step-by-step solution is available using the options described in Student:-Basics:-OutputStepsRecord.  The options supported by that command can be passed to this one.
